I understand the feeling of being overwhelmed. The best way to get help on MHF is to post one question per thread and to demonstrate all that you know/what you need help with. If you know nothing about how to do the question then post what you have gone over in class and what you think might be a way to start. Welcome to MHF.

Edit by Mr F: Also, please type your questions rather than attaching them as image files. I see no question content that would make that an overly difficult thing to do.

I have closed this thread. Please feel free to post your questions again, following the advice you've been given.
